Sequencer:- 2 banks with up two 8 bars per instrument- Adjustable play modes from 1 to 8 bars and random modes- Song Mode with a length of up to 99 bars

Choose between two virtual analog synthesizers and the drum machine for each channel:

Analog- Modeled after legendary monophonic synths of the '70s- For fat sounding bass and powerful lead sounds- 3 oscillators with 6 different waveforms- Each oscillator can be tuned precisely and has a warmth control for the typical analog sound- Attack, Decay, Sustain and Release envelope generator- Pitch wheel- Low-pass filter (24dB/oct, 4-pole) with knobs for cutoff, resonance and an ADSR envelope generator

* Please note that for recording in real-time with the Analog synthesizer you will need a low latency Android device with at least Android 4.2. Read more about audio latency on our FAQ: http://www.mikrosonic.com/faq

I like this app alot. So much so I paid actual money for it. However the record function does not work. Well. It works but the problem is the file doesn't play back. Tried to upload to soundcloud. Also failed. Fix this issue so I can 5 star the app. Not being able to share the music is a buzzkill.

RD4 Groovebox This app is BOSS! I recommend it to anyone looking for a great rhythm sequencer machine. I would like a distortion fx but you can do that with the envelope filter. However it still does a fantastic job and is well worth its very affordable price.

Best app out there to create music on my phone!! Great Synths, and versatile drum machines. It won't do the work for you, but as a musician I don't want it to. Great stuff!!

Simple and fun. I really enjoy playing with this app. Very simple and intuitive. It's like having a setup that includes a combination of drum machines and 303s. The analog synths are a little bit of a let down, but it is only $5.

Good For Creativity As someone who uses tangible gear this is a simple little APP. I'm using it on a tablet and i'd imagine it would be a pain to use on a phone. Most of the sound generated is flat which is convenient if you plan on mixing into a real soundboard later for recording. I prefer apps due to their price range as well as their simplicity. If you want to cut your teeth into something that's daw like this is a good intro without breaking the bank and getting super frustrated.

If you like making EDM try this It was the TB303 emulation that drew me to this app. And it also has great emulations of the famous TR X0X drum machines also from Roland Corp. Great for catching ideas when you're not in a studio.

Excellent for casual use Exporting loops is excellent for exporting to SPC. Wishlist: #1 while I can use the beats- or baseline-track to emulate a metronome, a dedicated one would be great #2 MIDI overvIP (rtpMIDI e.g.) would be great.

stiLL Like iT ii.know iT can do better@ , so where's more oF the good.stuFF oF its "new.improvements" _stuFF Like more "voices" _ & beyond the 4tracks & bassLines or beyond the 1/8th.note expressions _ when ii 1st began its was RD3 , then RD4 , so whats wit that? _ there shouLd be an "[RD5] wit more accompaniment" by now _ ii.started wit [DX7].unowned in '86 & work'd my.way upto severaL PSR.series! _ but this "mikrosonic?" does WEB.services _after that? _its getn HEARD thats the chaLLenge! _

It's missing a sound bank This could be soooo much more had they just added a sound bank. It's not asking for much is it? I've paid good money to get stuck with the same sound that I can add effects to.. Well big whoop!! There's no point if I can't vary my sounds is it! Thoroughly disappointed, I wish there was a way to get a refund on these app selling things. Update on 7/3/15 (3/7/15 for the Americans) THIS IS SUCH A TERRIBLE APP. IT WON'T ALLOW YOU TO EVEN ADD TWO LAYERS OF MUSIC ON THE SAME LOOP. DON'T WASTE YOU MONEY AS I HAVE

Very fun toy Cool toy to spend some time during train trips etc, if you're into machine music. I find it a bit pricey though considering it's shortcomings such as the lack of pan and shuffle. The reverb sounds awful and I'd like to control drum sound and level independently. And maybe I'm doin it wrong but I can't export the song to wave, only loop. Nevertheless it gives me a lot of fun, the sound is good, timing accurate and it runs smoothly on my single core armv7 1GHz with small screen(!). Recommended!

Maybe Ok? It was Ok last time. Now it automatically generates sound when you are recording. Maybe, Maybe not? Problems with it in Analog 1 & 2. I still like playing with it cause you can make music, but has problems. Take the chance of messed up music. Thank you.

Great for laying out musical ideas I use this app on my phone and tablet to lay out musical ideas when I'm not able to use ableton. Only gripe is I wish I could zoom out easier in the midi writing utility.....especially on my 10 inch tablet. Otherwise so much awesome and easy packed in here.

Superb I can't praise this app highly enough. Wonderful balance between feature set and simplicity, and still being updated. Spent dozens of hours enjoying making music while on the plane, in bed, on holiday, etc. Thank you mikrosonic!
